CATAMARAN.

Specification of Letters Patent.

Application led Julie 17, 1919. Serial No. 304.957.

To all whom z't 'may concern:

Be it known that I, DANIEL MACIUK, a citizen of Poland, residing at 68 Cameron street, Toronto, Province of Ontario, and Dominion of Canada, have invented certain new and useful Improvements in Catamaran's, of which the following is a specification.

This invention has for its object the provision of a sea-going boat of the catamaran type which is practically unsinkable.

A further object is to provide a boat with attachments whereby it may be engaged between a paill of elongated floats, or de tached therefrom so as to be used in the ordinary manner.

These and other objects are attained by the novel construction and combination of parts hereinafter described and shown in the accompanying drawings, forming a material part of this disclosure, and in which- Figure 1 is a perspective view showing a boat made in accordance with the invention and indicating the application of the inven tion.

Fig. 2 is a side elevational View of the boat.

Fig. 3 is a fragmentary side View of the rear portion of the boat, parts being shown in a different position from that in Fig. 2, and

Fig. 4 is an enlarged partial side elevational view of the same, indicating the manner of attaching the boat to the floats.

Referring to the drawings in detail, the numeral 10 indicates the main portion of a pair of non-submergible floats, which may be 4made either cylindrical or polygonal, provided with conical points 11 at each end. Fixed upon the body are encircling bands 12, and extending between the bands are tangential connecting bars 14, whereby the floats are held in fixed parallel relation.

The boat 15, which may be of any preferred type, is preferably formed with relatively parallel sides and covered except at the cock pit 16, may be provided with a motorto actuate the propellers 17 at the rear, adjacent to the rudder 18, beyond which may be extended va ladder 19, whereby the deck and cock-pit can be easily entered.

Pivoted upon pins 20, extending out from the sides of the boat 15, are a pair of levers having actuating handles 21, movable in arcuate guides 22, fixed upon the sides of the boat, the levers being held in either of their operative positions by pins 23, passing through the guides 22 and lever elements 21 near their handle ends, the pins being maintained against loss by chains 24, secured to pins 25, upon which are also secured the ends of heavier chains 26, securing pins 27, adapted to pass through pairs of parallel elements 28, and openings formed in the parallel flanges of these elements 28 fixed upon the lower ends 29 of the levers.

The pins also pass through openings provided in the connecting bars 14 so that the boat may be rigidly secured to the floats, or disengaged from the floats as may be desired.

From the foregoing it will be seen that an effective device has been presented whereby a boat may be secured between a pair of floats, operating in the manner of a catamaran, preventing the boat from rocking or sinking, the floats being propelled by the power of the boat when secured thereto and are steered and otherwise manipulated in the ordinary manner.

Having thus described my invention what I claim as new and desire to secure by Letters Iatent, is-

1. In a catamaran, the combination with a pair of cylindrical floats vhaving conical ends, bands surrounding said floats, connections extending between said bands whereby said floats are held in spaced parallel relation, a boat adapted to be received between said floats, said boat containing a cock pit, means for access thereto, and levers pivotally secured upon the sides of said boat at the front and rear thereof, engageable with the connections between said floats.

2. In a catamaran, the combination with a pair of cylindrical floats having conical ends, bands surrounding said floats, connections between said floats whereby they are held in spaced parallel relation, a boat having parallel side walls engageable between said floats. levers pivoted on the sides of said boat, outstanding lugs formed with the lower ends of said levers adapted to engage with the connections between said bands, and means for engaging and disengaging said lugs and said band connections.

In testimony whereof I have aflixed my signature.

DANIEL MACIUK.
